Ontario to appeal court's ruling upholding federal carbon-pricing law

The federal government's carbon charge is constitutionally sound, says Ontario's top court, with the five-judge panel rejecting a challenge from Premier Doug Ford's government to the validity of the carbon-pricing law.

The federal government's carbon pricing scheme is constitutionally sound and has the critical purpose of fighting climate change, Ontario's top court ruled in a split decision on Friday.

The Greenhouse Gas Pollution Pricing Act, enacted in April, is within Parliament's jurisdiction to legislate in relation to matters of "national concern," Chief Justice George Strathy wrote on behalf of the court.

"Parliament has determined that atmospheric accumulation of greenhouse gases causes climate changes that pose an existential threat to human civilization and the global ecosystem," Strathy said.

"The need for a collective approach to a matter of national concern, and the risk of non-participation by one or more provinces, permits Canada to adopt minimum national standards to reduce [greenhouse gas] emissions."

Ontario's Progressive Conservative government under Premier Doug Ford, who calls the carbon charge an illegal tax, had argued the act is a violation of the Constitution because it allows the federal government to intrude on provincial jurisdiction.

The provincial government announced it will seek leave to appeal the decision to the Supreme Court of Canada. "We know, as do the people of this province, that the federal government's carbon tax is making life more expensive for Ontarians and is putting jobs and businesses at risk," Ford said in a statement released Friday afternoon.

"We promised to use every tool at our disposal to challenge the carbon tax and we will continue to fight to keep this promise."

During four days of submissions in April, Ontario insisted the act would undermine co-operative federalism. Provincial lawyers argued the federal government would end up with the power to regulate almost every facet of life — such as when you can drive, where you can live, or whether you can have a wood-burning fireplace.

For their part, federal lawyers argued the province was fearmongering. The act, they said, was a legitimate response to potentially catastrophic climate change by creating an incentive for people to change their behaviour.

'They are not taxes': chief justice

To the delight of environmental groups, the majority of the Appeal Court agreed with Ottawa, rejecting any contention the carbon levy is an illegal tax.

"They are regulatory in nature and connected to the purposes of the act," Strathy wrote. "They are not taxes."

Cutting greenhouse emissions cannot be dealt with "piecemeal" and must be addressed as a single matter to ensure its efficacy, the court said. "The establishment of minimum national standards does precisely that."

In a dissenting opinion, Justice Grant Huscroft said climate change did not amount to an "emergency case" and warned against allowing rhetoric to colour the analysis. Carbon pricing is only one way to deal with greenhouse gases, he said.

"There are many ways to address climate change, and the provinces have ample authority to pursue them."

Federal Conservative Leader Andrew Scheer agreed with Huscroft. "Ontarians have said loud and clear that they do not want Justin Trudeau's carbon tax," Scheer said in a statement Friday.

"The good news is that after Oct. 21, provinces will no longer have to fight the Liberal carbon tax in court. My first action as prime minister will be to scrap Justin Trudeau's carbon tax and help Canadians get ahead."

Federal act applies in 4 provinces

The federal act currently only applies in four provinces with conservative governments — Ontario, Manitoba, New Brunswick and Saskatchewan — which Ottawa says don't meet national standards. Alberta is in the process of its own challenge against the law.

"Alberta has a strong and credible plan to reduce emissions without punishing Albertans with a retail carbon tax on people trying to heat their homes or drive to work. This makes a federal carbon tax redundant here," Premier Jason Kenney said in a statement Friday.

"We are committed to our right to make policy choices in our own jurisdiction. We will be making that case to the federal government, to the Supreme Court of Canada and to the Alberta Court of Appeal in our own reference case this fall."

Federal Environment Minister Catherine McKenna called the judgment good news for Canadians who believe climate action is urgent. She took aim at those opposed to the act, such as Ford, Kenney and Scheer.

"It is unfortunate that Conservative politicians ... continue to waste taxpayers' dollars fighting climate action in court rather than taking real action to fight climate change," McKenna said in a statement.

In all, 14 interveners — among them some provinces, Indigenous groups and environmental and business organizations — lined up to defend or attack the law, with most siding with Ottawa. Some observers said the challenge was more about politics than the environment.

In May, Saskatchewan's Appeal Court, in a 3-2 decision, upheld the carbon pricing law as constitutional. The Supreme Court of Canada has said it will hear Saskatchewan's appeal of that ruling in December — after the federal election.

'Nail in the coffin' for conservative premiers

Stewart Elgie, a professor of law and economics at the University of Ottawa, called the decision a "big nail in the coffin" for conservative premiers challenging carbon pricing.

"Two provincial Appeal Courts have upheld the federal law, and it is very likely the Supreme Court will do the same," Elgie said. "It would be great if Doug Ford took the $30 million he's using to fight carbon pricing, and instead used it to fight climate change."

Ontario Green Party Leader Mike Schreiner said he was relieved the courts rejected Ford's attempts to make Ontario a "rogue actor in the fight against the climate crisis."

Peter Tabuns, a Toronto MPP and the Ontario NDP's critic on climate issues, said the challenge was a "political stunt" aimed at helping the federal Conservatives in the fall election.
